Lucas Amorosino says Argentina plan to target Australian playmakers Quade Cooper and Bernard Foley on Saturday.
The pair meet in Perth in the fourth round of Rugby Championship fixtures, with both teams eyeing their second victories of this year's tournament.
Cooper and Foley have been paired at fly-half and inside centre by Wallabies boss Michael Cheika throughout the Championship but they are still to truly gel.
Australia have a long history of playing two first receivers at 10 and 12 and Cheika will be hoping they can finally turn on the style in Perth, having shown signs of promise in last week's win over South Africa.
Amorosino admits the duo's talent makes them extremely dangerous but says Argentina plan to make the most out of their unfamiliarity by targeting them whenever possible.
"We have to put the pressure on Quade Cooper and Foley," he told reporters. "They play with really good skill.
"The idea is to put pressure on those players so they don't feel comfortable, and after that we have an opportunity to have the ball as much as possible."
